PATENT OFFICE 7 MOP WRINGING APPARATUS Edward Pavek, Minneapolis, Minn.

Application February 23, 1933, Serial No. 657,956

' 20 Claims. (01. 15-261) This invention relates to a mop wringingapparatus, and while the apparatus is capable of being secured to a pailand mounted on the pail in various manners, it particularly isillustrated as adevice having means supporting it upon the edge of thepail and being'readily removable from the pail.

It is an object of this invention to provide a .mop wringing apparatuscomprising plates relatively swingable toward and from each other tosqueeze a mop therebetween, means for swinging one of said plates andmeans simultaneously engaging the other plate to move it with increasingleverage as said plates approach each other.

It is a further object of the invention to provide a mop wringingapparatus comprising a pair of plates relatively swingable about a pivottoward and from each other to squeeze a mop :therebetween, means forswinging one of said plates, means simultaneously engaging the otherplate to move it toward said first mentioned plate, said last mentionedmeans being movable toward :the axis of said pivot as said platesapproach each other. i g F It is a further object of the invention toprovide a mop wringing apparatus comprising a frame, a plate pivoted insaid frame, a second plate connected to said first mentioned plate, a

roller carried by said second plate and a cam engaged by said roller assaid first mentioned plate is swung to move said second plate towardsaid first mentioned plate, together with a guide means for said roller.

These and other objects and advantages of the invention will be fullyset forth in the following description made in connection with theaccom-v p-anying drawings, in which like reference characters refer tosimilar parts throughout the several views and in which:

Fig. 9 is a top plan view of Fig. 8; and

Fig. 10 is a view in side elevation of Fig. 8, as seen from the leftthereof, Figs. 8, 9 and 10 be- 5 ing shown on an enlarged scale.

Referring to the drawings, particularly Figs. 1 to '7, a pail 20 isshown adapted to contain wash Water such as usually used in moppingfloors. A frame member 25 is shown, and while this frame 10 member mightbe secured to or supported in the pail in various ways, in theembodiment of the invention illustrated it is shown as having a'pair ofside plates 2 la, each of which has a slot portion Zlb at one sideforming a tongue or hook 2lc adapted to extend over the edge of the sideor partition 26a of the pail 20. The said side or partition extends intothe slot 2H) and the side portions Zia have their edges extendingdownwardly along the side or partition a and said 20 side portionsextend substantially at right angles to said side or partition. The sideplates 2 la are connected by headed rivets 22 having their heads at theouter sides of the side plates, which rivets have thereon and extendthrough sleeves or tubular members 24 engaging the adjacent sides ofsaid side plates. A pivot member 25 extends through side plates 2 la,having washers 26 at the outer sides of said plates held in place bypins or split key members 21 extending through pivot 25 30 at the outerside of the washers 26. It may be stated that side plates 2 la areconnected at their lower ends by a portion 2ld extending therebetweenadjacent the bottom of pail 2B. The pivot 25 extends through arcuateslots 28a formed in the parallel side portions 28?) of a plate 28. Plate28 as clearly shown in Figs. 1 and 3 extends substantially the distancebetween the side plates 2 la and plates 28b extend in parallel relationand parallel to the side plates Zia. The side portions 282) have aplurality of holes 2811 therethrough. Plate 28 is slightly curved at itsbottom and formed with hinged lugs through which extends a hinged pintle29 also extending through hinged lugs at the bottom of the plate 30interfitting with the lugs on plate 28 so that plates 28 and 30 arehinged together at their bottom portions. Plate 30 extends between theside portions 28b, and above the same, said plate having a portion. 30abent outwardly and downwardly at its upper end." Portion 30a has a slot391) formed therein through which extends a member or bar 3! connectedat its lower portion to the rear of plate 30 by some suitable fasteningmeans such as the rivets 32.

forwardly of plate substantially at right angles, and side portion 3Iais bent into U shape so as to have parallel side portions. Said parallelside portions are each provided with a slot 311) and a stud 33 extendsthrough said slots, being threaded at each end to receive nuts 34 whichengage the washers 35 disposed at the outer sides of portion 3 la andextending across the slots 31b. Stud 33 has a sleeve 36 thereonextending between the sides of portion 3 la and on which is'journaled aroller 31 having a concave groove in' its periphery. It will be seenthat the stud 33 can be disposed in different portions in the slots 3lb,the same being movable when nuts 34 are loosened and being capable ofbeing tightened inthe desired position by said nuts. The plate 28 at itsouter side or the side remote from plate 30 has a pair of bearingsleeves 38 secured thereto in any suitable manner, as by welding, and arod 39 extends through and between said sleeves, being 'journaledtherein and having at its ends rollers 40 secured thereto. The rollers40 rest upon and are adapted to travel along a cam surface 280' formedon the top of each side plate'2 Ila as shown in Fig. 1. Curved guiderods 4| are secured in the plates Zla at the outer end of the cam track7 28d and extend in curved formation some distance over said cam tracks.

In operation, when a mop is to be squeezed;

the same will be disposed between the plates 28 and 30 as they are inthe position shown in Fig. 1. The operator then disposes the mop stick42 in the position shown in dotted lines in Fig. '1', the same beingdisposed between the sides of portion 3la and in'contactwith the roller31. The operator can now swing the handle to the left as shown in Fig. 1and this causes'plate 30 to swing about the axis of pintle 29 and movetoward plate 28. As plate 38 is thus swung, the lower end thereof movesto the right and due to the resistance of plate 28 and the presence ofthe mop between said plates, pivot 25 moves to the left in slot 28a.

' The plates finally reach approximately'the position shown in Fig. 6.It will be s'eenthat the lower end of the plate 28 will be moved totheright in I the lower end of plate 36 and the rollers 40vril1 be drawnalong the cam track 280'.

rollers 40 thusapproaches the axis of the pivot 25 and an increasingleverage is had moving the Y plates together as bar 3| and mop handle42'are swung to the left. The mop will thus be thoroughly squeezed andthe water therefrom will run out between the bottoms of the side platesand through the holes 28d into pail 20. The operator can now swing themop stick 42 tothe right and thus move it parallel to plate 30 until itis out of "without the necessity of the operator bending over the pail20. It is more difficult to bend down over the pail and operate a leveror handle to squeeze the mop than it is to perform the operation abovedescribed and with the described operation the operator does not have tob'ring'his face down over the pail 20 which usually-com tains hot water.

In Figs. 8 to 10 a bar 45 is shown, which will" be used in place of thebar 3i. The bar 45 has The axis of a rivet 46 secured therein passingthrough an aperture in a hook member 41 having one portion extendingparallel to one side of the bar 45 and having a protuberance 47a thereonengaging the side of the bar 45. A spring 43 surrounds rivet 46, bearingat one end against member 41 and at its other end against a washer 49held in place by a screw 56 threaded into the rivet 46 and having aslotted head. Spring 48 is of coiled formation with a larger diameteradjacent member 41 than adjacent the washer 49. Member 41 extends aroundthe bar 46 and has a substantially semi-cylindrical hook portion 471) atits outer end.

In operation, when the mop is placed between plates and 30, the operatorwill swing the mop handle 42 into the hook portion 41b of the plate 41and bar 45 will be swung to the left as already described for bar 4!. Itwill be noted that bar 41 can swing about the axis of rivet 46as'indicated by the dotted lines in .Fig. 8 and can "also swing towardand away from the plate 45' as indicated by the dotted lines in Fig. 9.

The mop stick 42 can thus be moved in a somewhat irregular path andplate 4'! will aocommodate-itself to such movement.

From the above description it is seen that applicant has provided asimple and yet very efficient structure of mop squeezing apparatus. Theapparatus is adapted to be removably supported in a pail as shown, or itmay be permanently secured in a pail. The parts are comparatively few innumber and can be strongly and ruggedly made. It is' obvious that thedevice will have a high degree of utility for the purpose intended. j Itwill, of course, be understood that various changes may be made in theform, details, ar-

- rangement and proportions of-theparts, without departing from thescope of applicants invention, which generally stated, consists in adevice capable of carrying out the objects above set forth, in thepartsand. combinations of parts disclosedand defined in the appended claims.
